test case

I'm using the pre-built llvm-gcc4.2-2.2-x86-linux-RHEL4 on debian. With the
attached test case (taken from the GCC 4.2.1 testsuite), I get:

$ ~/llvm/llvm-gcc4.2-2.2-x86-linux-RHEL4/bin/llvm-gcc -c cleanup1.C
[It runs for a couple of minutes and uses up about 1 GB of virtual memory,
then...]
llvm-g++: Internal error: Killed (program cc1plus)
Please submit a full bug report.
See <URL:http://developer.apple.com/bugreporter> for instructions.

If I try the same thing with a normal release of GCC 4.2.1 it completes in a
couple of seconds and uses less than 100 MB.
